That's a tough problem, i have a couple natural friends as well. I was a natural as well back in the States but since i moved over to england and theres a big culture difference and the way they speak difference, i've had to kinda restart and get culturally acclimated. Anyways, enough of me, let's get some answers for you, i've got a few possible solutions.
If you don't want to emberass the friends, you'll need to work fast and isolate the target real quick. This will help because it's one on one and it's clear you're doing your thing. If your friend comes over and cockblocks you, he'll look like a dick considering it's obvious you're interested in that girl.
Secondly, you could use body positioning and lock him out of the set (assuming it's a 1 set). That wouldn't be too emberassing would it?
Finally, if you're both already in the group and he's got the attention, up your energy. I always do this in big group things where i just go BOOM and explode with energy, making all the girls play games, going kino, teasing, loads of fun stuff like that right out of the blue. Like im on a sugar rush or on coke (Obviously not though). This always gets the attention on me, i have time to pull off a few quick moves and isolate the target as well as me having the choice of who my target is because i become the center of attention and the most fun/entertaining guy to be around with.
I hope this helped mate, take care!
